Will be as good as impossible to find a new one and if someone has a new one somewhere my guess is that it would be well over a grand for it as seen quite a few good secondhand one's sell for 400 - 500 quid.
I know someone looking for a good uncracked dash and he's more than happy to splash out 500 quid for it !!!
I have a very good one from a RS16i stored in my loft with only one tiny crack about quarter an inch long, tempted to put it on the bay but confident it will only go up in value so will probably just leave it where it is for another few years !!
